> Instead of only defining the set of columns from the data table that make up an index, you should be able to use expressions.  For example:
>       CREATE INDEX upper_last_name_idx ON person (UPPER(last_name))
> Then in queries that use UPPER(last_name), we can replace them with column references to the index table.
